Import Bearing Steel Ball For Precision Bearing — Buy in wholesale FOB from Supplier in China

Bearing steel balls for precision bearing applications from Zhong Shan H.R.T. Precision Steel Ball Co., Ltd. are manufactured from high-carbon chromium bearing steel conforming to AISI 52100 and 100Cr6 grades, with hardness ratings spanning G10 to G100 under AFBMA standards. Diameters range from 0.5 mm to 250 mm according to client requirements, and the product carries ISO-9001 and TS-16949 certification. These balls serve electric motors, automotive wheel hubs, pump assemblies, and high-speed machinery where minimal friction and superior wear resistance are critical.

The material composition leverages high-carbon chromium steel with excellent surface quality and hardness uniformity. Grade G10 represents the tightest tolerance class, suitable for ultra-precision spindles and aerospace-grade bearings, while G100 serves general industrial applications. Surface integrity, sphericity, and dimensional consistency are controlled through cold-heading, grinding, and lapping processes typical of the bearing ball industry. The chrome steel variant offers corrosion resistance in moderate environments, though sealed bearing designs are recommended for aggressive chemical exposure.

Primary buyers include OEMs in automotive supply chains, industrial equipment manufacturers, and aftermarket distributors serving maintenance, repair, and operations. The product also suits ball screw assemblies, linear motion guides, and even non-traditional applications such as ink and paint grinding media. Packaging and export configurations are not specified in the source data, so confirm carton quantities, rust-preventive oil, and vacuum-sealed options with the supplier. MOQ and lead time should be discussed directly, as no binding figures appear in the listing.

Zhong Shan H.R.T. Precision Steel Ball Co., Ltd. operates from No.71 Shenchong Industrial Park in Zhongshan, Guangdong Province, postal code 528400, placing it within the Pearl River Delta manufacturing corridor. The supplier holds a harbor trust tier and has a response rate of 0.00 percent with zero average response hours recorded, which suggests limited engagement data rather than non-existence. Buyers should verify current responsiveness through direct enquiry, as the profile signals a registered entity with a physical address but no demonstrated communication history.

The company markets bearing steel balls across a 0.5 mm to 250 mm diameter spectrum, targeting precision engineering sectors from automotive to food processing. No workforce size, annual revenue, client roster, or years in operation are disclosed in the source profile, and these should not be assumed. The TS-16949 certification indicates past or present automotive quality system compliance, though buyers should request the current certificate scope and expiry date. Direct verification of production capacity, inspection equipment, and sample availability is advisable before committing to volume orders.
